Patent CA-2034657-A1 (CA)
Title: Filter dryer
Inventor: LOUGHRAN JAMES F
IPC: B01D53/26
Filed: 1991-01-21
Abstract: An air filter dryer for adsorbing moisture from an air flow of the type typically found in a pneumatic power system comprises a housing having an inlet fitting and an outlet fitting arranged such that the filter dryer can be installed directly in line with system piping.  The filter dryer also includes a series of filters arranged symmetrically at each end of the housing.  Included in the series of filters are dispersion filters which collect moisture in the air flow and also disperse the air evenly across the housing.  An oil removal filter is located adjacent each dispersion filter in the filter arrangement, and acts to remove any oil comtaminants from the air flow.  This filter dryer further includes a silica gel desiccant, located between the respective oil removal filters, which adsorbs moisture from the air stream.  The air then passes through the second symmetrically arranged series of filters, and exits through the outlet fitting.

Filed: 1990-09-28
Abstract: ABSTRACT             Method and device for automatic image segmentation by textural analysis The  device  for  automatic  image  segmentation according to the invention comprises a data processor associated with a network of automata organised in three levels; the inputs of each of the automata are weighted by adjustable coefficients; the number of automata of the first level is equal to the number of characteristic values computed from observation windows taken firstly in a set  of  examples  of  image  zones  having  different textures: their learning by the network permits adjust-ment of the weighting coefficients of the automata of the network until all the examples of the same texture lead to the same configuration, characteristic of this tex-ture, output by the network.        The segmenting of an image then consists, on the basis of sets of characteristic values computed on image zones to be analysed, in analysing the output of the network in order to deduce therefrom the texture of the zone.        Application to the segmentation of aerial images or medical images, for example, and more generally to any type of image in which the regions are distinguishable through their texture.

Title: Brake pressure reducing valve assembly
Inventor: FARR GLYN P R
IPC: B60T8/28
Filed: 1990-05-08
Abstract: A deceleration conscious brake pressure reducing valve assembly comprises a valve body (2) defining an inlet chamber (3) and an outlet chamber (4) connected by way of passages (9, 10) formed in a piston (7). A ball (15) is mounted within a cage portion (16) of the piston and rests on an inclined ramp surface (17). A valve member (13) is provided for closing the passage (11) by engagement with the seat (12) formed on the piston (7). A spring (9) maintains the components in the illustrated position until the outlet pressure acting over area A0 is sufficient to overcome the force of spring (9). If at this point deceleration of the vehicle has reached a predetermined level, the piston (7) will move to the left and the ball (15) will run up the ramp (17) in order to close the valve (13). If, however, the vehicle is heavily laden so that the pressure at which the piston (7) starts to move is insufficient to produce a deceleration which will move the ball (15) up to the ramp (17), the piston (7), ball (15), and valve (13) will move as a unit to the left and the passage (11) will remain open.  The ball (15) will run up the ramp (17) to close the valve (13) when system pressure produces sufficient deceleration. At pressures above cut-in pressure the valve acts as a metering valve to provide a progressive increase in outlet pressure as the inlet pressure rises. The valve is unable to close, regardless of vehicle deceleration or attitude, at pressures below that necessary to move the piston (7) against the force of spring (9). The ball (15) is substantially isolated from hydraulic fluid flow and is accordingly unaffected by changes in fluid viscosity. In the event of very rapid piston (7) movement the inertia of the ball (15) holds the valve member (13) in the illustrated position to ensure rapid closure of the valve.

Title: Attachment member for insulation panels
Inventor: ROTHENBUHLER WALTER
IPC: E04B1/76
Filed: 1991-12-20
Abstract: A member (1) secured in place by a fastening element (5) attaches insulation panels (2) to a structural component (A). The fastening element (5) is driven into the structural component (A) by a setting tool (8). To prevent damage to sector-shaped parts (6) extending radially inwardly in the entrance to a passageway (4b) through the attachment member (1), a diametrically increased section (4d) of the passageway extends axially inwardly from the entrance. The diametrically increased section (4d) has a diameter increased by twice the thickness of the sector-shaped parts (6) compared to the adjacent inward diameter of the passageway, and an axial length at least equal to the free length of one of the sector-shaped parts (6). When the muzzle end (8a) of the setting tool (8) is inserted into the passageway (4b), the sector-shaped parts (6) are bent inwardly within the diametrically increased section (6d) of the passage-way (4b) and, in combination with the passageway serve as a guide surface for the setting tool. The sector-shaped parts (6) rebound when the setting tool (8) is removed from the passage-way. When a coat of plaster (9) is applied over the insulation panels and the attachment members, the plaster penetrates behind the sector-shaped parts (6) and effects a back-gripping action.

Title: Edible fats
Inventor: VAN MEETEREN JOHANNA A
IPC: A23D7/02
Filed: 1992-02-03
Abstract: The processability of a margarine or other edible spread fat blends and the properties of the resulting products are to a large extent determined by the crystallisation behaviour of the fat blend. Problems of delayed crystallisation are known in the art of margarine or other spread manufacture, in particular, it is common knowledge in margarine blend formulation that interesterification of fats quite often results in slower crystallising fat blends and often fat blends which are impractically or inconveniently slow to crystallise. We have now determined that the crystallisation of margarine fats from a supercooled melt can be accelerated by the use of a triglyceride having a trans fatty acid at the 2-position, preferably a 1,3-saturated-2-trans-unsaturated (FTF) tempering accelerator. These include, in particular the HTH TAGS where H is stearic or palmitic, and especially PEP.
